An old guy orders a hamburger, French fries and a drink. He sits down, unwraps the burger, cuts it in half and then puts one half in front of his wife. He counts the French fries and then puts half of them in front of his wife. He takes a sip of the drink, his wife takes a sip and then she sets it down between them.
The people all around them are all thinking, "That poor old couple ... all they can afford is one meal."
As the old guy starts to eat his fries, a young guy comes over to their table and says, "I'd be glad to buy you folks another meal."
The old guy says, "W-we're just fine. W-we're used to sharing everything."
The people closest to them see that the little old lady hasn't eaten one bite. She just sits there watching her husband eat and takes turns sipping the drink.
The young guy comes back and says, "Are you sure I can't buy you folks another meal?"
This time the woman says, "No, thanks, we're very used to sharing everything."
Finally, as the old man finishes and is wiping his face with a napkin, the young guy comes over and says to the little old lady who still hasn't eaten a bite of food, "What are you waiting for?"
She says, "The teeth."
